摘　　要：以生态足迹模型和物质流分析为核心工具,对2002—2011年石家庄市的生态足迹和物质流代谢进行了分析与可持续性评价。结果表明:(1)研究时段内石家庄市人均生态足迹总体上呈上升趋势,2011年达到6.964 207hm2/人,人均生态承载力由0.251 515hm2/人下降到0.213 777hm2/人,此期间内历年均为生态赤字,至2011年人均生态赤字已高达6.750 43hm2/人。表明石家庄市对自然资源的利用超出了生态承载力的范围,生态发展处于不可持续状态。(2)石家庄市直接物质输入总体呈增长趋势,由2002年的57 695.72万t增加到2011年的75 434.04万t,区域资源开采活动不断增强,具有资源依赖性,资源开发比较粗放,区域内隐藏流(DHF)成为环境压力的主要来源。(3)与2002年相比,2011年物质生产力(MP)增加了1.78倍,数据显示其在物质利用效益方面有了改善,但资源利用效率仍较低。Ecological footprint model and material flow analysis were used to analyze and evaluate Shijiazhuang ecological footprint and sustainability metabolic material flow from 2002 to 2011. The results showed that： （1） in the study period, Shijiazhuang City, the per capita ecological footprint overall presented the upward trend, it reached up to 6. 964 207 hm2/person in 2011, per capita ecological carrying capacity decreased from 0. 251 515 hm2/person to 0. 213 777 hm2/person, ecological deficit was significant during this period, and the per capita ecological deficit had reached to 6. 750 43 hm2/person in 2011, these showed that use of natural re- sources in Shijiazhuang City was beyond the scope of ecological carrying capacity, and ecological development was not sustainable; （2） overall direct material input of Shijiazhuang City presented increasing trend from 5.77 ;K 108 t in 2002 to 7.54 X 10a t in 2011, regional resource extraction activities were growing with resource dependencies, and resource development was also more extensive, the hidden region stream （DHF） had be- come the major source of environmental stress; （3） compared to that in 2002, material productivity （MP） in- creased by 1.78 times in 2011, the data showed its effectiveness in substance use had improved, but the use efficiency of resource was still low.
